What is a hard bounce?
Every time you send your emails, or your newsletters, gambling data indonesia phone number some of them may be rejected by the recipient's mail server. This is what we call a bounce or an email that could not reach the inbox of a contact to whom it was sent. You should know that there are two types:
Soft bounces are emails that cannot be delivered temporarily, due to a temporary problem with the server or because the recipient's mailbox is full;
Hard bounces are emails that are sent but cannot be delivered in any way, for reasons we will discuss below.
What causes a hard bounce?
Some of your emails might be generating or have already generated bounces, and now you are wondering what the reasons behind this are. Please read the following carefully, because these are the main causes :
a non-existent email address , perhaps because the recipient registered by mistake or because it is an old email address that has already been disabled;
the domain name does not exist , therefore the part of the address after the “@” has been misspelled or belongs to a site that has disappeared;
The recipient's mail server has blocked delivery - this occurs when the provider's antispam filters are very high and could block, a priori, messages sent from a specific email address or IP address;
a technical error on the servers , a fact that is very rare to occur, but it is good to know that this possibility also exists.
What are the damages caused by hard bounces and how to avoid them
Having too many hard bounces will seriously damage your email marketing strategy : in the long run, your IP reputation will be affected and if this gets significantly worse, email servers will start blocking your messages or automatically sending them to the SPAM folder .
Once an IP address is not considered trustworthy and safe, it is inserted into a blacklist , a virtual list of senders labeled as spammers, and to remove your IP from that list is anything but a simple task, and involves several other problems.
